Title: Improvements relating to the manufacture of organic pigments and moulding powders
IPC: C08K5/23
Filed: 1947-04-17
Abstract: The polyvinyl benzals obtained by the process described in the parent Specification are treated with a leuco derivative of a vat dyestuff in aqueous medium, the polyvinyl benzal then being washed free from excess leuco derivative, then oxidized to effect the dyeing, the product being finally washed and dried.  The polyvinyl benzals are derived from polyvinyl alcohols which may contain ester and/or acetal groups, and aldehydes of the benzene and naphthalene series.  When deep shades are required the polyvinyl acetals preferably contain hydroxy groups.  The vat dyestuff may be an indigoid or anthraquinoid dyestuff, including indigo, thioindigo and the halogen, amino, alkyl and alkoxy derivatives of indigo, anthraquinone, benzanthrone, pyranthrone, anthanthrone and dibenzanthrone.  The reduced dyestuff may be used in conjunction with a dispersing agent such as sodium sulphoricinoleate or sodium oleyl sulphate or with a stabilizing agent.  When dyed, the resins may be mixed with other thermoplastic resins or thermosetting resins, fillers, plasticizers or pigments. The products may be used as pigments or moulding powders, in paints, lacquers and coating compositions. Mottled effects may be obtained by incomplete mixing with other dyed or undyed polyvinyl benzals.ALSO:The polyvinyl benzals obtained by the process described in the parent Specification are treated with a leuco derivative of a vat dyestuff in aqueous medium, the polyvinyl benzal then being washed free from excess leuco derivative, then oxidized to effect the dyeing, the product being finally washed and dried.

Title: Improved apparatus for handling barrels and like metal containers during fabrication in a conveyor line
IPC: B21D51/26
Filed: 1951-05-02
Abstract: 681,074. Feeding blanks. RHEEM MANUFACTURING CO. May 2, 1951 [Nov. 10, 1950], No. 10329/51. Class 83 (iv). Apparatus for moving metal drums between a conveyer line and a press during manufacture comprises a fixed frame, rods carried at each side of the frame by spaced pairs of pivoted arms by which the rods may be raised and lowered, a movable frame slidable along the rods, carrying depending hooked arms for engaging within the ends of the drums. Bolted to a press 12 beside a conveyer 11 is the fixed frame comprising a plate 15 and a horizontal tubular member 13 to which are welded laterally-extending lugs 17. Horizontal rods 21 are supported by arms 20 pivoted to the lugs 17 and a movable frame comprising angle-bars 27 and a cross-brace 36 is slidably mounted on the rods. Pairs of depending hooked arms 38, 39 are pivoted to short arms 31 welded to the angle irons and coupled together by links 48 operated from a pneumatic cylinder 47 so as to move the arms to engage or disengage the drums. The movable frame may be raised or lowered as a whole by means of a pneumatic cylinder 26 coupled to the arms 20 by links 23. In operation, when a partially-made drum arrives opposite the press, a finger 52 depending from the conveyer actuates a switch 51 which operates a multi-way solenoid valve to supply compressed air to the cylinders 26 and 47 so that the drum is gripped by the arms 38, 39 and lifted from the conveyer. As it rises, an angle bar actuates a switch 54 to start a motor 55 which drives a chain connected with the anglebars by a rod 60, so that the drum is carried into the position shown in dotted lines in Fig. 1. When the leading edge of an angle-bar actuates switches 63, 64, the motor 55 is stopped and the press is actuated to form an opening in the side of the drum and to secure a thread ring or flange therein. The rising of the press tools actuates a switch 66 which starts the motor 55 in the reverse direction until the actuation of another switch stops the motor and supplies air to the cylinders 26 and 47 to lower the drum on to the conveyer. In a modification, the above operation on the drum may be carried out by two presses, the first of which merely forms the hole. The movable frame associated with the second press then has a pneumatically operated centring rod to engage the hole in the drum before the drum is moved horizontally beneath the press tool.
